What happens if you get too much cyanide?
The body can be routinely exposed to small amounts of cyanide and needs to be able to handle this small amount on an everyday basis. There is an enzyme that converts cyanide to a form that can be eliminated from the body. However, if there is too much cyanide, then this enzyme is overwhelmed.
What is the name of the kit for cyanide?
In the hospital, a common treatment is the Cyanide Antidote Kit. It is also known as the Lilly Kit, Pasadena Kit or the Taylor Kit.

As EMS cannot really use the first two drugs in the Cyanide Antidote Kit for a smoke inhalation victim for reasons mentioned before, it has been proposed that perhaps the third drug, Sodium Thiosulfate, can be given alone.
How long should you be in the emergency department for cyanide?
Patients who have ingested hydrogen cyanide solutions or patients who have direct skin or eye contact should be observed in the Emergency Department for at least 4 to 6 hours (Hall and Rumack 1998).
What is the effect of cyanide on the body?
In humans, cyanide combines with the ferric ion in mitochondrial cytochrome oxidase, preventing electron transport in the cytochrome system and bringing oxidative phosphorylation and ATP production to a halt. The inhibition of oxidative metabolism puts increased demands on anaerobic glycolysis, which results in lactic acid production and may produce severe acid-base imbalance. The CNS is particularly sensitive to the toxic effects of cyanide, and exposure to hydrogen cyanide generally produces symptoms within a short period of time (ATSDR 2006).
How is hydrogen cyanide absorbed?
Hydrogen cyanide is absorbed well by inhalation and can produce death within minutes. Substantial absorption can occur through intact skin if vapor concentration is high or with direct contact with solutions, especially at high ambient temperatures and relative humidity. Exposure by any route may cause systemic effects.
How long to wash clothes with hydrogen cyanide?
If the patient's clothing is wet with hydrogen cyanide solution, quickly remove contaminated clothing while flushing exposed skin and hair with plain water for 2-3 minutes (preferably under a shower), then wash twice with mild soap (HSDB 2007).
How long after exposure to cyanide can you be discharged?
Patients who remain asymptomatic 4 to 6 hours after exposure may be discharged with instructions to seek medical care promptly if symptoms develop (see the Hydrogen Cyanide—Patient Information Sheet below).
Can cyanide be fatal?
Ingestion of hydrogen cyanide solutions or cyanide salts can be rapidly fatal (ATSDR 2006). Treatment of ingested cyanide salts is similar to treatment of oral hydrogen cyanide poisoning because cyanide salts form hydrogen cyanide in acidic conditions.
Is hydrogen cyanide lighter than air?
Perception of the odor is a genetic trait (20-40% of the general population cannot detect hydrogen cyanide); also, rapid olfactory fatigue can occur. Hydrogen cyanide is lighter than air (HSDB 2007).
What is the treatment for cyanide poisoning?

How can cyanide poisoning be detected?
In cases where no suspicious substances are observed in the scene of the death, the presence of cyanide in the victim’s body can be confirmed chemically using a colorimetric test, followed by a laboratory analysis using a gas chromatography–mass spectrometry (GC-MS).
Is cyanide poisoning hard to detect?
Summary: Cyanide exposure can happen occupationally or in low levels from inhaling cigarette smoke — or from being poisoned by someone out to get you. The effects are fast and can be deadly. But because cyanide is metabolized quickly, it can be difficult to detect in time for an antidote to be administered.
What is the most common cause of cyanide poisoning?
Smoke inhalation, suicidal ingestion, and industrial exposures are the most frequent sources of cyanide poisoning. Treatment with sodium nitroprusside or long-term consumption of cyanide-containing foods is a possible source.
Can cyanide poisoning be cured?
Cyanide poisoning is a treatable condition, and it can be cured if detected quickly and treatment is started immediately. Most people die because the diagnosis is not made quickly enough, or it is not considered from the start. Cyanide poisoning is rare, so the treating physician should be alerted of the possibility.
Which drug is used in cyanide poisoning?
Lorazepam is the drug of choice; midazolam and phenobarbital are second-line agents. Cyanide antidotes are the key medications for hydrogen cyanide (HCN) poisoning. Hydroxocobalamin (HCO, vitamin B-12) is the first-line therapy for cyanide toxicity.
How long does cyanide stay in a body?
A small amount of cyanide can also be converted to carbon dioxide which leaves the body through exhalation. Some cyanide can react with hydroxycobalamin to form vitamin B12. Most cyanide leaves the body within one day.
What is the major effect of cyanide?
Cyanide poisons the mitochondrial electron transport chain within cells and renders the body unable to derive energy (adenosine triphosphate—ATP) from oxygen. Specifically, it binds to the a3 portion (complex IV) of cytochrome oxidase and prevents cells from using oxygen, causing rapid death.
